` Application led February 24, 197. Serial No. 150,756.

which will be particularly adapted for,

bitching a plow or a gang plow to atractor.

When a tractor is utilized for drawing a plow it is 'frequently foundextremely diiiicult if not impossible to turn a square cor ner either tothe right or to the left, this being due largely to the unvaryingresistance exerted by the plow at the hitching point. To overcome thisobjection is one of the objects of the invention..

A. further object of the invention is to produce a bitching device ofsimple and improved construction whereby the motion of the tractor inturning a corner will cause adjustment of the bitching point or point ofdraft to be effected in one direction or the other, thereby avoiding theobjectionable side draft and facilitating theturning of a sharpcorner.

With these and other ends in View which will readily appear as thenature of the invention is better understood, the same con- 'sists inthe improved construction and novel arrangement 1 and combination ofparts which will be hereinafter fully described and particularly pointedout in the claims.

In the accompanying drawing has .been illustrated a simple and preferredform oi" the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

ln the drawing: l

Figure 1 is a top plan view of a device constructed in accordance withthe invention.

Fig. 2 is a side view of the same.

Fig. 3 is a sectional View taken on the line :s-s in rig. i.

Fig. 4 is a horizontal sectional view taken on the line M: in Fig. 3,

Corresponding parts 1n the several figures of the drawing are denoted bylike characters of reference.

il. housing is provided, the same being con structed of top and bottomplates 15 and 16 of lsosceles triangular forni having a base ofrelatively great length, said plates beingv spaced apart by spacingblocks 17 located in the angles adjacent to the base, and con* nectedtogether by bolts or fastening members 18 extending through said blocks.The

inner side walls of the spacing blocks 17 are` rounded to providepockets 19. The top and .bottoni plates are provided with lflanges' 20-extending between the apex of the housingand the corners adjacent to thebase thereof, said flanges, which are suitably spaced apart,constituting track rails for a pair of rollers 21 carried by a bitchingstrap 22 one end of which extends' within the housing. 23 is i hitchingbar which is mounted adjacent to the base of the housing,l saidbarybeing provided with lugs 2st entering recesses in the spacing blocks17 where said lugs are engaged by the bolts or fastening members 18whereby the hitching bar is securely connected with the housing. Saidbar is provided with a plurality of apertures 25 for the passage offastening members 2G whereby it is connected with the rearward ends ofbitching straps 27 the forward ends of whichare adapted to be connectedwith a tractorwith respect to which the hitching bar is thus capable ofbeing transversely adjusted.

Secured within the housing directly in front of the apex thereof is asocket member 28 having a concave pocket or recess 29 adapted-to receivethe rollers 21 when the tractor isv backed for the purpose oi' backinga, plow or other implement connected with the bitching strap.

From the foregoing description, taken in connection with the drawinghereto annexed, the operation and advantages oit' this invention willbereadily understood. It will be seen that when the tractor begins to turneel either to the right or to the lett the housing again straighten ont,the initial or normal position of the rollers 2l Wiii be automaticallyresumed. Should it be desired to hack the implement drawn by thetractor, hackwerd movement of the latter will place 'the rollers 21 inengagementwith the pocket 29 of the socket member 28, and e straightpush in a rearward direction 'will thus be exerted.

Having thus described the invention, 'what is claimed es new is:

l. In a device of the ciass described, n triangular housing comprisingtop and hot- 'toin plates having track anges at the sides thereof,spacing blocks at the corners of said plates adjacent to the bese, saidblocks having rounded side walls producing' pockets, a bitching straphaving a portion extending Within the housing between the track ienges,and track engaging rollers carried hy seid hitching strep.

2. ln a device of the class described, a triangular housing comprisingtop land hottom plates having track flanges at the sides thereof7spacing blocks at the corners ot saidplates edjecent to the base, saidblocks front of the apex thereof, said apex extending,` in a rearwarddirection.

3. In a device of the class described, a.

housing of Vtrian,guiar form having track ra'iis at the sides thereof,spacing ineinhers et the corners adjacent to the hase of the housing,said spacing blocks having recesses formed therein, a hitching harhaving' lugs engaging; said recesses, connecting bolts eX- tendingthrough the top and bottoni plates of the housing', spacing clocks andthe lugs, and hitching straps adjustahly connected with the hitchingbei', in combination with a hitching strap one end of which extendsWithin the housing and is provided 'with track engaging roilers.

n testimony whereof l aix my signature.
